Abstract

The utility model relates to an automatic water intake device of a sewage treatment tank, and belongs to the technical field of sewage control devices. The device comprises a primary treatment tank, a secondary treatment tank, a primary water intake pipe, a secondary water intake pipe, a tertiary water intake pipe, a water discharge pipe, a water level detector, a controller, a water pipe valve control motor and a switch valve. A required water level value can be set in the controller according to water treatment requirement, the water level detector transmits the detected water level value to the controller in real time, the value is compared with a preset value in the controller, and the water pipe valve opening is regulated according to a comparison value. The automatic water intake device of the sewage treatment tank improves the sewage treatment control precision and automation degree of the sewage treatment tank, can realize unattended treatment, and has relatively high credibility and usability.

Description

A kind for the treatment of tank automatic water inflow device

Technical field

The utility model relates to a kind for the treatment of tank automatic water inflow device, a kind of three grades of sewage disposal unmanneds particularly, and the occasion that the water inlet control accuracy is higher is used.

Background technology

The sewage disposal device of large-scale wastewater treatment plant generally is made of a plurality of processing units, and the water inlet of each processing unit is distributed equally by water distribution system.The water yield equilibrium of distributing to each processing unit just can reach best treatment effect.At present, the water distribution system of sewage work is generally by the UNICOM of conventional gate and pipeline, flows directly into each processing unit, and its flow can not be regulated control.In actual motion, because the drag characteristic difference between treating pond results in blockage, and cause overflowing of coagulation pond, and must Attended mode, level of automation is lower.

The utility model content

The utility model has proposed a kind of automatic feeding water scheme for the unattended requirement of sewage work's tertiary treatment pond water inlet.

Technical scheme provided by the utility model is:

A kind for the treatment of tank automatic water inflow device comprises that coagulation pond, second-stage treatment pond, tertiary treatment pond, one-level water inlet pipe, secondary water inlet pipe, three grades of water inlet pipes, rising pipe, level switch, controller, aqueduct valves control motor, opening-closing valve; One side in described coagulation pond is connected with the one-level water inlet pipe, be connected with the secondary water inlet pipe between the opposite side in coagulation pond and described second-stage treatment pond, be connected with three grades of water inlet pipes between described second-stage treatment pond and tertiary treatment pond, an end in tertiary treatment pond is connected with described rising pipe; Be provided with opening-closing valve on described one-level water inlet pipe, described opening-closing valve and described aqueduct valve are controlled motor, controller, level switch and are connected successively, and described level switch is connected with described coagulation pond.

Preset the water level value in the coagulation pond in controller, level switch detects actual water level, and is transferred in controller, compares with predefined numerical value, controls the aperture of motor and valve according to comparative figure, has realized the automatization unmanned.

Description of drawings

Fig. 1 is the utility model treatment tank automatic water inflow device schematic diagram;

Wherein, 1-coagulation pond; 2-second-stage treatment pond; 3-tertiary treatment pond; 4 one-level water inlet pipes; 5-secondary water inlet pipe; Three grades of water inlet pipes of 6-; The 7-rising pipe; The 8-level switch; The 9-controller; The 10-aqueduct valve is controlled motor; The 11-opening-closing valve.

Embodiment

Below in conjunction with accompanying drawing, the technical solution of the utility model is described further:

As shown in Figure 1, a kind for the treatment of tank automatic water inflow device comprises that coagulation pond, second-stage treatment pond, tertiary treatment pond, one-level water inlet pipe, secondary water inlet pipe, three grades of water inlet pipes, rising pipe, level switch, controller, aqueduct valves control motor, opening-closing valve; One side in described coagulation pond is connected with the one-level water inlet pipe, be connected with the secondary water inlet pipe between the opposite side in coagulation pond and described second-stage treatment pond, be connected with three grades of water inlet pipes between described second-stage treatment pond and tertiary treatment pond, an end in tertiary treatment pond is connected with described rising pipe; Be provided with opening-closing valve on described one-level water inlet pipe, described opening-closing valve and described aqueduct valve are controlled motor, controller, level switch and are connected successively, and described level switch is connected with described coagulation pond.Preset the water level value in coagulation pond 1 in controller 9, level switch 8 detects actual water levels, and is transferred in controller 9, compares with predefined numerical value, controls the aperture of motor and valve according to comparative figure.

Controller comes the by-pass valve control aperture according to height of liquid level.When in the coagulation pond, liquid level was low, controller sent out large-signal, controlled the motor forward, and valve is rotated counterclockwise, and flow increases; When in the coagulation pond, liquid level was high, controller sent the pass small-signal, controlled motor reversal, and valve turns clockwise, and flow reduces.
